Keita Suminoe has two older (not blood-related) twin step-sisters who love him in a lustful way and have no problems expressing it. They even like to compete about it; much to the laughter of his friends (which he usually endures without problems). One day they come to his school to give him his lunch, resulting in him getting angry due to the atmosphere. To counteract his anger, they confess their tender feelings for him in front of everyone and leave. Feeling sorry he chases after them and says that he'll study hard in order to get in the same high school as them.

One of the ecchi greats, must read

After reading up to Chapter 38(the most recent chapter released when this was written) I can safely say that KissXSis is my favorite ecchi manga of all time. Why is it so good? For starters, the main character, Keita, isn't searching for an unobtainable girl that eventually falls for him. His twin, non blood-related step sisters, Ako and Riko, are the ones in love with him, and they openly show it(even infront of the parents, which fully approve and support it).

The two sisters are what make the manga so popular. They each want to get Keita, they each kiss him ALOT and because of that there's plenty of conflict between the two. The funny part is how each sister tries to isolate Keita and herself, and what they have planned.

There are alot of chapters that push the ecchi to the max, where one more step and it would be considered Hentai. Look at it this way: By chapter 10, Keita has gotten dragged into situations by either Riko or Ako that exceed everything that other ecchi manga like to-LOVE-ru and Love Hina did in all their chapters.

Another thing that should be noted is that this manga loves to poke fun at relationship situations looked down upon by society, such as Student-Teacher relationships.

At this point
Spoiler (highlight to view)
By chapter 8 or so(don't remember which exactly) Keita has a flashback of when he was young and how he wanted to marry both his sisters. His father replies by saying that it's illegal, which saddens the young Keita. In later chapters, he openly admits that he loves them both, which makes it clear that Keita will have to make a decision one day: Who will he choose? The sweet, closet-pervert Ako? Or the tough, honest Riko?

It's because of the decision, and how they both are given the same amount of focus, that I really hope it doesn't have a Harem/improper ending. to-LOVE-ru, a series I fell in love with, had the same problem with the ending. Keita needs to choose one of his two sisters, and we, the readers, should get a foreshadowing when the manga nears its end, about who Keita will choose. His sisters love him too much, and he loves them too much, for Keita to not pick any.

In short, excellent read, every chapter forces you to read the next!

Cheap thrills, for the most part.

The premise: two sisters lust for their conveniently non-blood related stepbrother, who is fairly resistant to their advances at first for obvious reasons, but PUBERTY! speaks pretty loud in his mind. Hilarity ensues... or does it?

KissXSis actually started out pretty funny, but the quality of the art and plot steadily as the author obviously ran out of ideas and just resorted to cheap, contrived incest-related ecchi scenes. The more recent introduction of some new rivals for Keita's affection has added some much-needed color for the series, but seriously, sometimes this manga gets you thinking that even the author has given up hope on making anything worth reading, relying on it as a mediocre, if steady, source of income instead.

I haven't watched the anime, but I hear it suffers from the same problems. I'm surprised that this was even popular enough to be animated in the first place, really.

A boy with cute twin sisters that isn't blood related with them. Add to this megane with weak bladder and female otaku sensei. Now this is some nice plot for Ecchi.

Honestly I'm glad it's not hentai. If it crossed that line well... It would probably suck. There's a story to it. If it were hentai, there goes the story. I discovered this through the anime OVA and I can't wait for the next episode (they better make one) and I can't stop watching the first one over and over.

This isn't bad but it really is lacking. It's got the twincest thing going for it of course but the way things progress you really get the feeling that it should just go into hentai territory already. Sweet sweet hentai...

Mahou-X did far more better work than Manhua's. I can't really accept the Manhua's translation. Since they r both voluntarily do it and got nothing than our gratitude, so I do not expect the best work. But still, I hope Manhua team comes to their sense and try to improve what ppl critisized about.

PS. I do little hope that this will become full H-Manga XD

manhua rev problem was mainly the fact that they love putting american slang around which doesn't make much sense in a manga... and in some cases apparently not there originally.

mahou-x typesetting could use improvement, and their grammar isn't perfect but they did not so far added things into it outside the original translation so as far as i'm concerned they have done a much better job at it.
